DESCRIPTION:Jean-Marie Droz (Bremen)\nVarious Quillen model structures can
  be constructed on categories of combinatorial objects. We will show that 
 classical graph theoretical notions\, like the core of a graph and the set
  of connected components\, are notions of homotopy types in specific Quill
 en model structures. However\, we will also demonstrate that\, often\, wha
 t could be regarded as natural candidates for homotopy types in a category
  of graphs cannot arise from a model structure. Finally\, we will consider
  the classification of all model structures on simple categories of combin
 atorial objects and count the model structures on a category of finite gra
 phs.
